I am writing a cover letter for my job application, and I am not sure which preposition is proper to use at a sentence as below. "Hereby, I am applying for the position of AAA (position title) in BBB (company name)."
I am not sure if "in" is the correct one or not. How about "at" or "of", instead of using "in".
- I am applying for the position of AAA (job title) in BBB (company name).
- I am applying for the position of AAA (job title) at BBB (company name).
- I am applying for the position of AAA (job title) of BBB (company name).
And if you can tell me why, I would appreciate. (Using proper preposition is the most difficult part for/to(?) me.)
Thank you in advance!
